The Twins' Michael Cuddyer led off the top of the fifth with a double, the only Twins runner in scoring position for the entire game. Danks induced a deep flyball out from Delmon Young, which allowed Cuddyer to advance to third. Brendan Harris hit a deep flyball to center field which was caught for an out by Ken Griffey, Jr. Cuddyer tried to score on the ball as a sacrifice fly, but Griffey delivered an accurate throw to home plate and White Sox catcher A.
